The point is that you can never just focus on or the other. For position players, they always both count.
I see what you are saying but I guess my feeling is there is some point at which you must sacrifice one for the other and that works both ways depending on the type of team you have. Although perhaps a slight offensive lean moreso than a defensive one.
For example if we kept improving our defense at a rate of 2:1 until we had the best glovemen in baseball, balls can still and will hit the ground, balls will still leave the yard etc. At what point must you find that balance?
